  •      Their display principle is: the back of the display screen is diffused by the LED light source, and uniformly irradiated on the transparent film on which the picture is drawn, thereby forming a clear and beautiful picture.

  •   Advertising machine LED display analysis: 
  •  
  •      As a traditional liquid crystal display device, the light source is CCFLS (Cold Cathode Fluorescent Lamp), which we can simply understand is the fluorescent lamp source for household use. The only difference is that the tube on the LCD advertising machine is very thin.
  •  
  •      The traditional liquid crystal display has certain disadvantages: it is that the color of the object itself cannot be displayed well, and the displayed object has a strange feeling compared with the actual one. The reason for the weird display is that the light it emits is not really the daylight we see. It is the light that is produced by refraction and is somewhat different from the light that our eyes are used to.
  •  
  •      It can be seen from the above that the display of the traditional liquid crystal advertising machine is a bit weird due to the light emitted from the back light box, and the color and the real color of the object are also deviated, failing to meet the requirements of the advertisement, and failing to satisfy the professional user. demand.
  •  
  •      In general, the emergence of LED advertising machines is more to replace the display problems of traditional LCD advertising machines, extending the color gamut range to 105% of the NTSC standard.
